This invention relates to a multi-tap and combinational alphanumeric data entry on a 12 key device. The [1] key on is labeled with the “.QZ”. Numbers are produced by activating ten numbered keys. Activating the [#] key backspaces. Activating the [*] key one or more times enters an alphabet mode. Activating [1]-[9] keys once produces left data, twice produces middle data and three times produces right data. Activating the [1] then [*] keys produces the “-” dash. Alternatively, simultaneously activating [1]-[9] keys and a left [*] key produces left data, simultaneously activating [1]-[9] keys and a middle [0] key produces middle data and simultaneously activating [1]-[9] keys and a right [#] key produces right data. Activating the [#] key enters a data character for the next data entry on the same previously activated key. Activating the [*] key, after entering a data character, produces the shift function. Activating the [*] key twice produces the backspace function. Activating the [0] key produces a space. Activating the [0] key twice produces a Tab or Enter function. Activating the [#] key twice re-enters the number mode. Activating the [#] and [*] keys enters a first punctuation/symbol mode, where activating [1]-[9] or [0] keys produces left data. Activating the [#] and [*] keys and the [*] again enters a second punctuation/symbol mode, where activating [1]-[9] or [0] keys produces middle data. Activating the [#] and [*] keys and the [*] two more times enters a third punctuation/symbol mode, where activating [1]-[9] or [0] keys produces right data. The alphabetic mode is automatically re-entered into after the punctuation mark or symbol is produced. An entered punctuation mark is followed by a space. Activating the [*] key after the punctuation mark and space is produced, deletes the space after the punctuation mark. Activating the [0] key after a period and space is produced, deletes the space after the period. Simultaneous two key entry increases data input speed by reducing the amount of entries required.
